Title: Semiconductor device

IPC: H01L29/778
Filed: 1989-02-03
Abstract: PURPOSE:To enable multichannels without generating dislocation even by using an InGaAs layer having a different lattice constant to a GaAs substrate as a channel layer by bringing the synthetic quantity of deformation to zero at every pair of a first compound semiconductor layer as the channel layer and a second compound semiconductor layer as an electron supply layer. CONSTITUTION:A non-doped i-GaAs layer 12 is formed onto a GaAs substrate 10 as a buffer layer, and three pairs of channel layers 14 and electron supply layers 16 are shaped onto the layer 12. That is, the i-In0.2Ga0.8As layers 14a-14c in thickness of 150Angstrom  as the channel layers and the n-In0.68Ga0.32P layers 16a-16c in thickness of 150Angstrom  as the electron supply layers are laminated alternately. Since the absolute values of positive deformation sigmax to the substrate 10 of the layers 14a-14c and the absolute values of negative deformation sigmay to the substrate 10 of the layers 16a-16c are equalized at that time, the thickness of the layers 14a-14c and the layers 16a-16c is made uniform. Accordingly, no dislocation is generated, thus realizing a change into multichannels.
